The Nest Learning Thermostat (4th Gen) is the premium choice for homeowners who want a thermostat that adapts to their lifestyle.

Owner reviews consistently highlight the large, vibrant display and the significant reduction in heating and cooling bills after installation.
Setup is straightforward for those comfortable with basic wiring, and the device integrates seamlessly with Google Home and other smart assistants. While the upfront cost is higher, the long-term energy savings and convenience make it a worthwhile investment for most households.

Best BudgetPros
- Attractive mirror display blends into decor
- Lower cost with essential smart features
- Simple Quick Schedule setup via app
Cons
- No auto-learning like the Learning model
- Display is smaller than the 4th Gen
The Nest Thermostat (2024) is the best entry-level option for those wanting smart home integration without the premium price. It features a sleek mirror finish that hides the screen when not in use and offers a Quick Schedule function that lets you set your weekly temperatures in minutes. Owners appreciate its minimalist design and reliable performance.
It works with the Google Home app and supports voice control through Google Assistant. While it lacks the adaptive learning of the higher-end model, its energy-saving features and remote control capabilities make it a solid choice for budget-conscious buyers.
Nest Thermostat E
Best ValuePros
- Auto-scheduling at a lower price point
- Frosted display is less intrusive
- Strong Eco Mode for energy savings
Cons
- Plastic build feels less premium
- Smaller display than other models
The Nest Thermostat E offers the core auto-learning features of the Learning Thermostat in a more affordable package. It uses a frosted plastic display that diffuses the screen content, making it less prominent on the wall. Owners report that its Eco Mode is effective at reducing energy use when no one is home.
It is a good middle-ground option for those who want the benefits of a learning thermostat but are not ready to invest in the top-tier model. The build quality is slightly less robust than the metal-ringed Learning Thermostat, but its performance is nearly identical for most users.
Nest Learning Thermostat (3rd Gen)
Best LegacyPros
- Proven reliability with years of owner feedback
- Farsight display shows time or temperature
- Lower cost than the 4th Gen
Cons
- Older hardware and design
- Display is smaller and lower resolution
The Nest Learning Thermostat (3rd Gen) is still a capable device for those who can find it at a discount. It features the same auto-scheduling and Farsight technology that made the line popular. Long-term owners praise its durability and consistent energy savings over many years of use.
While it lacks the larger screen and some refinements of the 4th Gen, it remains a solid choice for those who want a proven smart thermostat. It is often available at a reduced price as retailers clear out older stock.
Nest Thermostat (2020)
Best SimplicityPros
- Very affordable entry point to Nest
- Sleek mirror display
- Simple manual scheduling via app
Cons
- No auto-learning feature
- Display is smaller and lower resolution
The Nest Thermostat (2020) is the most basic and affordable model in the lineup. It offers a clean mirror display and allows you to set a manual weekly schedule through the Google Home app. Owners who prefer to control their own schedule without the device learning find this model to be straightforward and effective.
It still provides remote control, energy history, and integration with smart home systems. For users on a tight budget or those who simply want a connected thermostat without the learning features, this model is a reliable and cost-effective choice.
What to check before buying a Nest Thermostat
Before purchasing, check your home's HVAC system compatibility. Nest thermostats work with most 24V systems, including gas, electric, oil, heat pumps, and radiant systems. You can use the online Nest Compatibility Checker on Google's website. Also, verify if your system requires a C-wire (common wire) for power, especially for the Learning Thermostat models. Many homes built after 2010 have a C-wire, but older homes may not.
Mistakes to avoid when choosing a Nest Thermostat
A common mistake is buying a model without checking if it supports your specific heating and cooling system, such as multi-stage heat pumps or systems with dehumidifiers. Another error is ignoring the need for a C-wire, which can lead to power cycling issues. Finally, do not assume all models offer the same features; the budget Nest Thermostat lacks auto-learning, which is a key feature for some users.
